This pair of sprockets will fit most models from 1928 to 1938. They can also replace earlier "morse chain" types used on earlier models and utilise standard chain also available (3/8 by 5/32) on this shop. M90 1928-33 uses S1-4605 which is ground to fit the outrigger bearing.
Please note that this magneto sprocket S1-4604 will not fit 350cc models 1, 2 and 8 except for the 1929 and 1930 M8
